Infants born low birth weight (LBW) and preterm were evaluated in a high-risk follow-up clinic and compared with infants born full term. A multivariate linear model was used to examine the overall differences on Bayley Scales of Infant Toddler Development (BSID-III) among three groups: full term, heavy LBW (<2,500 g ≥2,000 g), light LBW (<2,000 g). Results indicated no significant differences in BSID-III scores between the groups. The BSID-III was used to extrapolate indicators of executive function (EF) components. Dimensions of Mastery Motivation (DMQ 18) was correlated with the EF components. Findings showed that both LBW groups scored significantly lower than the full-term group on the EF components which include attention, plan/organize, working memory, and inhibit. Implications for research is discussed.

低出生体重和早产婴幼儿的执行功能

低出生体重 (LBW) 和早产婴儿在高风险随访诊所接受评估，并与足月出生婴儿进行比较。多变量线性模型用于检查三组之间贝利婴儿发育量表 (BSID-III) 的总体差异：足月、重 LBW (<2,500 g ≥2,000 g)、轻 LBW (<2,000 g)。结果表明，各组之间的 BSID-III 评分没有显着差异。BSID-III 用于推断执行功能 (EF) 组件的指标。掌握动机维度 (DMQ 18) 与 EF 组件相关。结果表明，两个 LBW 组在 EF 组件（包括注意力、计划/组织、工作记忆和抑制）方面的得分明显低于足月组。讨论了对研究的影响。
